After insisting for months that it was leaning toward replacing the 737 with a new airplane, Boeing decided in 2011 to outfit the 737 with new, more-efficient CFM International LEAP-1B engines. The newly dubbed "737 MAX" matched Airbus' move to put new engines on its A320 line. Here, a model of a 737 MAX 8 is pictured on Tuesday, Aug. 30, 2011, in Renton. The first one is scheduled for delivery in 2017.
